Car jerks/hard kick when accelerates Sign In

I have a 2006 f150 truck 5.4 gas engine. 110000 miles It starts great no engine nosie, runs greats. All of a sudden after the engine gets warm I go to accerelerate( fast) from a stop and my truck kicks hard and then acts like it wants to stall. I changed my fuel filter and cleaned the throttle box but the issue is still happening. I'm 99% sure it's not a transmission issue and my check engine light does not come on. My spark plugs were changed out about a year ago from a mechanic. Any other suggestions.

A ad MAF will give a symptom like that but it need more investigation.

scan for codes even if light if off.


a second test would be fuel pressure.
